A nurse is reviewing the list of current medications for a client who is to start a new prescription for carbamazepine. The nurse should identify that which of the following medications interacts with carbamazepine?
Nicotine transdermal system
Beclomethasone
Estrogen-progestin combination
Diphenhydramine
The Correct Answer is C
Choice A rationale:
Nicotine transdermal system is not known to have a significant interaction with carbamazepine.
Choice B rationale:
Beclomethasone is not known to have a significant interaction with carbamazepine.
Choice C rationale:
Carbamazepine can induce the metabolism of estrogen and progestin, potentially reducing their effectiveness in birth control. Women taking these combinations should use alternative contraceptive methods.
Choice D rationale:
Diphenhydramine is not known to have a significant interaction with carbamazepine.

Correct Answer is B
Explanation
Choice A rationale:
A BUN level of 16 mg/dL is within a normal range.
Choice B rationale:
A potassium level of 5.3 mEq/L is higher than the normal range (typically 3.5-5.0 mEq/L). Triamterene is a potassium-sparing diuretic, and if the client's potassium level is already elevated, it should be withheld to prevent hyperkalemia.
Choice C rationale:
A sodium level of 142 mEq/L is within a normal range.
Choice D rationale:
An albumin level of 4 g/dL is within a normal range.
Correct Answer is D
Explanation
Choice A rationale:
IV bolus administration of potassium is not appropriate due to the risk of cardiac arrhythmias.
Choice B rationale:
The formulation of potassium (potassium chloride) is appropriate for IV administration.
Choice C rationale:
Potassium chloride is typically diluted in normal saline (0.9% sodium chloride) for IV administration, not dextrose.
Choice D rationale:
The prescribed infusion rate of 30 mEq of potassium chloride over 30 minutes is too rapid and could lead to adverse effects, such as cardiac arrhythmias. The nurse should clarify the prescription and discuss a slower infusion rate with the provider.
